PROCESS OF WINDING.

Application filed May 15, 1903.

T all whmn it Wmy concern.-

Be it known that I, ARTHUR J. STRONG, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Processes of lVinding,of which I declare the following to be a full, clear, and exactdescription.

My invention relates to an improved method of winding successiveconvolutions of continuous material upon any desired object or work; andit is among the purposes and objects of my invention to provide aneconomical and rapid method of winding any desired length of suchmaterial upon work of various shapes, and it is particularlyadvantageous and applicable to the winding of material, such as wire,upon ring-shaped objects or cores.

Referring to the accompanying drawings, Figure 1 represents a specificform of device which may be advantageously used in carrying out myimproved method or process. Figs. 2 to 9 represent various diagrammaticviews showing the various steps of my process.

J ournaled in a stationary frame are two shafts 21 and 22, fast to theouter ends of which are pulleys 23 and 24, respectively. Upon the otherends of the shafts 21 and 22 are made fast pulleys 25 and 26,respectively, over which extends a belt 27 A crank-handle 28 is madefast to the end of the shaft 21, and it is thus obvious that when thecrankhandle is rotated in the direction shown by the arrow the pulley 23will be rotated and the belt 27 will impart a similar and simultaneousrotation to the pulley 24.

Fast to the central portion of the stationary frame 20 is asupporting-arm 30, provided with a suitable clamping device 31, which isadapted to have clamped beneath it any desired work which is to bewoundsuch-, for example, as the ring 40. (Shown in Fig. 1.) As will beseen in Fig. 1,this ring is situated between the pulleys 23 and 24,preferably in the middle, and, if desired, the supporting-frame 30 maybe adjustably attached to the stationary frame 20, so as to swing thering in any desired position in a horizontal plane or in a verticalplane.

Serial No. 157,301. (No model.)

Although my improved process is of course by no means limited to thewinding of wire material, however, for convenience I wish to refer tothe material as wire, and I will now describe the method by which thewinding is to be effected.

Referring to Fig. 2, the free end of the wire which is to be wound uponthe ring is first passed under the lower pulley 24 and then upwardthrough the ring 40. The end 50 is then led over the upper pulley and isthen tied or made fast in any suitable way to that portion of the wireimmediately following in such manner as to make a continuous band ofwire leading over both pulleys, as shown in Fig. 3, and from the knot 51the remaining portion of the wire 52 extends outward ready to be used inthe manner to be described. It will be observed from Fig. 3 that thering 40 is so situated with reference to the pulleys 23 and 24 that oneof the strands of wire may pass through the central portion of the ringand the other strand may pass outside of the ring without coming incontact therewith. As soon as the wire is tied, so as to form acontinuous band in the manner just described, the pulleys 23 and 24 arethen rotated in the direction shown by the arrows in Figs. 1 and 3, andit is obvious that by having the band of wire reasonably tight upon thepulleys the friction of the wire upon the pulleys will cause the band torun along with the pulleys just as a belt would do, and thereby theremaining portion of the wire 52 is carried along by means of thisrunning band in such manner that successive convolutions of wire will bewound upon the pulleys, as shown in Fig. 4, and the wire may thus bewound on to the pulleys until the desired length of wire which is to beused in winding has been reached and there remains the other free end 53of the wire. As soon as this point has been reached this free end 53 isfirmly made fast to that portion of the ring included between theconvolutions of wire in the manner shown in Fig. 5. As soon as this hasbeen done if the pulleys 23 and 24 are continued to be rotated in thedirection shown by the ar- 1 row in Fig. 5itis obvious that the end 53will be drawn taut and the rotation would be stopped unless perchancethe friction between the wire and the pulleys is so slight that thepulleys may still rotate without carrying the convolutions of wire withthem. However,

at this point the strand 53 is taken hold of by lutions of wire willimmediately take up this sition shown in Fig. 9 is reached.

slack portion caused by so removing the strand 53 from the pulley 23,and the downward movement of this strand in the direction shown by thearrow in Fig. 6 will then bring the wire into the position shown in Fig.7 in which the strand 53 now extends downwvard to the pulley 24:. Thenby repeating this operation of plucking off this strand 53 from thelower pulley 24: in a similar manner more slack is left, as shown inFig. 8, and the continued rotation of the convolutions of wire about thepulleys will again cause this slack to be taken up until the po- At thispoint it will be observed that a complete smaller or contractedconvolution 60 has been wound upon the ring, and it is apparent that bysimply continuing this operation of rotating the pulleys 23 and 24, andthereby continuously rotating the bands or enlarged convolutions of wireand at the same time plucking off the winding strand from the pulleys inthe manner described the slack caused by so plucking off this strandwill be taken up by the continued travel or rotation of the enlargedconvolutions, and there will result a series of contracted or smallereonvolutions wound upon the ring, as shown more in de tail in Fig. 1.

Of course the operator may vary the speed of rotation to suit hisfacility in handling the various winding-strands, and he may guide thewinding and force together the various smaller convolutions as they arewound upon the ring if it be desired to wind these convolutions closely.Furthermore, the ring 10 may be held somewhat loosely beneath the clamp31, so that it may be rotated in a horizontal plane to bring newwinding-surface into play as fast as desired. The belt 27 is notessential to be used, for the strands of wire themselves will act as abelt ordinarily; but if the belt is used the strands will not have to bedrawn so tight at the start, but will be natu' rally rotated by thecombined rotation of the pulleys 23v and 24:.

Of course various forms of machines may be used to rotate these pulleys,to provide friction-drives for the pulleys, if desired, or to provide anautomatic feeding device for the ring adapted to bring the unwoundsurface of the ring into winding position; but

my invention does not concern the form of machine to be used for such apurpose, but is intended to cover broadly this improved process ofwinding, and my invention covering the machine for use in such a processwill be reserved for a future application.

It is to be understood, of course, that the process herein described isapplicable not only to ring-shaped bodies, but also to bodies of othercurved shapes which cannot be rotated in order to do the winding, owingto the fact that other portions of the body would cross the path oftravel of the winding material, or is even applicable to the case ofstraight bodies which ordinarily could be wound by rotating the bodyitself and allowing the material to be wound thereon, but which it maybe impossible or else undesirable to rotate either because of theirunwieldy nature or of their frail nature or for other reasons.

The process herein described is particularly adaptable to the winding ofinsulated wire upon circular ring cores, for in methods here- .tofore inuse it has been customary to wind upon a bobbin all of the wire desiredto be wound upon the core and then pass the bobbin through the core timeafter time,unwind ing the wire from the bobbin onto the core as fast asthe successive cycles of movement were made, and of course if much wireis to 5 be wound upon the ring the size of the bobbin is so great thatthe bobbin could not in such case be passed through-the ring, whereas inmy case the ring need be only large enough to receive the variousstrands of wire which pass through it at the start, and it is evidentthat for any given length of wire which it is desired to wind upon thecore the number of strands passing through the ring may be decreased byincreasing the distance between the pulleys, thereby making fewerseparate strands, but compensated for by increase in the length of thesestrands. It is also evident that the pulleys may be of any desireddiameter, being merely so situated that the inner set of strands shallnot interfere with the inner sides of the ring, and in case of suchlarger diameter of the pulleys a greater contact-surface is obtainedbetween the pulleys and the wire, whereby the wire is less liable toslip upon the pulleys.

It may be noted that the same result may be reached by starting with thefree end of the wire to be wound, passing this free end through thering, around the upper pulley 23, down outside the ring, around thelower pulley 24, through the ring again, and thus continue thisoperation and so wind up upon the pulleys successive strands orconvolutions, as before, and when the other end of the wire is reachedthere will thus be two free ends. Either of these free ends may now beattached to the ring, and the other end may be made fast to itsimmediately adjacent strand, so as to follow around with it when thepulleys are subsequently rotated, and as to which end is attached to thering depends the direction of rotation of the band of strands, it beingevident that if the first free end (which has just been passed throughand through the ring) is now attached to the ring, ready for winding,the direction of rotation of the band of strands must be the reverse tothat which it had in the preparatory process of winding the strands uponthe pulleys, for it is necessary that the direction of rotation be suchthat the slack caused by successively plucking the winding-strand fromthe pulleys may be taken up by reason of the direction of rotation; butif the other end of the wire were attached to the ring the retation ofthe strands must be continued in the same direction as in thepreparatory winding in order to take up the slack, as above described.

It is of course more convenient to use the method first described forthe preparatory winding; but the other method would serve the purpose,and it is to be understood that my invention is not to be limitednecessarily to one or the other of these specific methods, but isintended to cover a broad process of forming around the work theseenlarged convolutions of material and then contracting these enlargedconvolutions successively into smaller convolutions upon the work bycontinued rotation of the enlarged convolutions to take up the slackmaterial.
